New PC USB HD and ntldr problem

When trying to backup the HD on my new PC with True Image, it failed to reboot with the ntldr missing error.
On investigation by removing the external USB HD, the PC rebooted OK. Even on a normal boot up with the USB drive connected, the PC failed to boot. The new PC has a 200 gig SATA HD installed and there does not appear any
settings in the BIOS to allow the PC to boot with the USB drive connected. My old PC with IDE drives had the USB drive permanently connected and always booted up without any problem.
Is this a known issue with SATA Drives? as I have no previous experience with them.

Was this when booting from the TI Recovery CD?

Did you install TI on the SATA drive prior to the problem? Did you create a SecureZone or enable the TI Recovery manager?

Does the system fail to boot even with a simple USB 128MB-1GB pocket drive attached?

TI was installed on the new PC and a boot disk made. Having read previous posts re Hidden partitions and as the PC used F10 to enter the recovery partition, I did not install Secure Zone or the TI Recovery manager.
The PC failed to reboot from the TI Boot disk with the USB drive plugged in. Remove the USB drive and the PC will boot using the TI TI Boot disk.
The system failed to boot with a USB 512 GB Stick or USB HD installed. The shop where the PC was purchased could not sort the problem out (If there was a problem?) so I had a refund, however still would like to find out if this is a problem with newer PC's and SATA drives.

I couldn't quite get how exactly the PC did not boot with Acronis Bootable CD. Did you get an "NTLDR file missing or corrupt" error when you plugged the USB drive? If so it is not the problem with Acronis software because Acronis Bootable CD doesn't use Windows files (such as NTLDR). If the problem was with booting into Windows after you plugged the USB drive then it may be the incorrect boot sequence in BIOS (the computer tried to boot with USB drive first) but people from the shop which sold the computer should have been able to sort this problem easily. It is difficult to investigate the problem now when you don't have the PC by your side but it seems that the problem is hardly related to Acronis software.

Hello Ilya, yes as originally stated the ntldr error showed when trying to boot from the Acronis Bootable CD. Also if any external device was plugged into any USB port the PC would not boot - "NTLDR file missing or corrupt" error 'no CD in drive' just a basic boot. The BIOS did not have any boot selection
options, even the shops techie was suprised and phoned the manufacturer, but they could not help. I know it is not TI problem, it just came to light while trying to back up the HD.
Thanks Peter.
